ROOF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 779,481, dated January'10, 1905.

Application filed June 29, 1904. Serial No. 214,675.

To all whom, it may concern.-

Be it known that LTIIoMAs HAvLooK KINGs- 'roN, a citizen of the UnitedStates, residing at bent upward therefrom.

Somerville, in the county of Middlesex and State of Massachusetts, haveinvented a new and useful Improvement in Roof-Brackets, of which thefollowing is a specification.

My invention relates to improvements in a folding roof-bracket forsupporting a temporary stage or platform upon the roof of a buildingwhile shingling, painting, or repairing the same or doing any other workon a building which requires a temporary staging upon the roof; and theobject of my improvement is to provide a light strong metallic bracketor stage-support which shall be compactly portable and conveniently,quickly, and safely attachable to and detachable from a roof, andIattain said object by means of the device hereinafter described andclaimed, and illustrated in the accompanying drawings, in which Figure lis a perspective of a roof, showing two of my improved brackets as whenin practical use thereon, with a dotted outline of the wooden platformsupported by the brackets. Fig. 2 is a side elevation of the bracket,shown as when its parts are in their relative positions in practical useand also showing in dotted outline the end of a platform-board thereon.Fig. 3 is a plan of the bearing-shoe detached from its cooperativeparts. Fig. 4: is an edge View of one of the pair of platform arms thatare pivotally attached to the shoe when the bracket is complete. Fig. 5is an edge view of one of the pair of supports which uphold the outerends of the platform-arms,

and Fig. 6 is a top view of the bracket when the parts are united andfolded into their most compact and portable form. 7

Referring to the drawings, the construction of the device as illustratedis as follows:

A bearing-shoe A, formed of metal, preferably sheet steel, is cut andpressed into shape, having integral penetrating points B B bent downwardand perforated lugs CC To the lugs are pivoted a pair of arms D D, whichserve to support, in cooperation with other brackets, a board orplatform resting upon the arms D D thereof.

When the brackets are in practical use, as illustrated in Fig. 1, theouter ends of arms D D are jointed by a bolt E to a pair of supports FF, which are formed with penetrating points Gr G G G The points G Gpenetrate the roof to such extent as to firmly secure them againstslipping and displacement, and points G G penetrate the wooden platform,which rests upon the bracket, and prevent slipping and displacementthereof on the arms of the bracket. The weight of the workman standingthereon forces the spurpoints into the roof and platform, and not onlythose of the supports F F, but also those of the bearing-Shoe A, therebyconfirming the stability of the staging.

This light portable folding bracket for Supporting a roof-stage for thepurpose of shingling, painting, or repairing the roof or doing any otherkind of work on a building which requires a temporary staging upon theroof has been practically proved to be exceedingly convenient anddesirable and safe in use. The supports F F being independently pivotedon bolt E afford an adjustment of the lower ends of the supports toadapt the bracket to slight inequalities in'the surface of the roof andto thus maintain a practically level platform above the same.

I claim- 1. A folding roof-bracket, comprising the combination of thefollowing parts, constructed, arranged and operated as described,namely: a bearing-shoe formed of sheet metal with integral penetratingpoints bent downward, and perforated lugs bent upward therefrom; a pairof platform-arms pivoted to said lugs, and connected by a bolt at theiropposite ends; and a pair of supports for said arms arranged between,and jointed to them by said bolt, and on their ends formed withpenetrating points arranged to enter, when in practical use, the roofand supported platform, all as specified.

2. A folding roof-bracket, embodying the combination of a bearing-shoeA, provided points G, G, G G all formed and arranged with downwardpenetrating points B, B, and to fold compactly upon the shoe with thesupperi'orated lugs G, C, extending upward; a ports within the arms, asshown and described.
